Harry L.. Owen, 4/ J L/ ATTORNEY cooling the coating composition'applied by the drip pot 13. If a heater is employed the material will be baked upon the wire. The wire isnow led around thesheave or drawing wheel 4 above referred to which draws thewire through the machine and thence -between the guide rolls 16 to the winding reel 17 upon which the wire s wound as the reel is rotated by the action of thebelt 18 which runs over the pulley 19.

The. object of employing a pulley is that it will slip to compensate for the variation of speed attained by the reel 17 due to the the wire from the wheel positive delivery of 4 and the increase in diameter of thewire upon the reel 17. I

The traverse mechanism for the wire winding reel 17 consists of a shaft 20 provided with right and left. handed screw threads andjournaled in the bearings 21 situated on the supporting frame of the shaft 20 is provided with a spline 22 to allow the driving pulley 23 to slide longitudinally thereon and atthe same time to rotate said shaftby, the engaging feeder or key. Upon the endof theframe 1 is pivoted the balance arm 24 which has attached thereto'the shifting lever 25 having its ends pivoted to the outer end of levers 26 mounted upon extensions 21. Attached to the inner end of the'levers 26 are the screw threadedboxes 28 which are thrown into and out ofengagement with the threaded shaft 20 by means of the in clined surfaces 28. The balance arm 24 has a pin and slot connection with the lever 25 so that when the balance arm is moved past its vertical position it will drop over in the direction in which it is being moved. When the pin reaches the end of the slot the momentum of the arm 24 shifts the lever 25 longitudinally and thereby turns the levers 26 on their pivots so as to shift one box 'into' engagement with the screw threaded shaft 20 and shift the other box out of engagement therewith to reverse the direction of movement of the reel. In order to move the balance arm 24 I provide a rod or roller 29 which projects into engagement with the inside edge of the flanges of reel 17. By this arrangement whenthe reel 17 travels far enough so that the wire has reached the end of its travel in one direction the balance arm 24 will be in the vertical position so that a very slight further movement throws the lever 24 over center and shifts the lever 25 which reverses the direction of motion of the reel as above described. This revers- 'tion since are in common use.

arrangement forms no part of my invendevlces of this general. character ing The asbestos coverer or applier 14 is constructedas follows: It comprises a housing or case 29 which is divided horizontally into two parts or members, the lower' part or member being secured uponthe supporting frame 1. Bearing brackets 30 are provided upon the lower member of the housing in which are rotatably mounted the carrying the 'V-shaped friction wheels 32 and the sprocket .Wheels 33 which are connected together by the sprocket chain 34. One of the shafts. 31 isprovided with'the sprocket wheel 50 (Fig. 1) which is driven by a chain 35 from the mains'haft. member ofthe housing 29 is provided with a bearing bracket 36 in which is mounted the V-shaped idle or retaining friction wheel 37. Ro-tatably and frictio'nally mounted upon said friction wheels 32 and 37 is a circular plate 38 provided with a V-shaped groove, in its periphery for receiving the friction wheels 32 designed to drive and propel the'plate and also to receive the retaining wheel 37. The center of the circular plate 38. is formed with an orifice 39 which allows the wire to pass therethr-ough. Parallel and adjacent to the rear surface of said plate 38 and integral with the lower member of th'ehousing 29 is a horizontal brace 40 having an orifice39. Secured'to this brace is an internal gear 41 in axial relation to the plate 38. Journaled in the plate 38 adjacent to the orifice 39 is a shaft 42 upon which is rigidly secured the pinion 60 meshing with the internal'gear 41. On the other end of the shaft 42 and upon the opposite side of the plate 38 is secured the driving pulley 43. Upon the same face of the plate 38 and between the pulley 43 and the orifice 39 are mounted the small rollers 44 and 45. These rollers are mounted upon studs 46 and 47 which are screw threaded into the plate 38.' It may here be stated that the diameter of the roller 44 and the ratio of the gearing for driving the same may be varied as required by the different sizes of the wire to be treated.

Rotatably mounted in the plate 38 with its end projecting therefrom is the shaft 48 having a pulley 49 which is driven by the belt 50 from the periphery of the internal gear 41. Upon the forward end of the shaft 48 is detachably secured a tape reel which is preferably of my novel construction shown in Fig. 7. This reel will be seen to consist of .a hub 51 formed with shoulders 52 and screw threaded ends 52. Detachably secured upon the ends of the hub 51 and retained in contact with the shoulders 52 by the nuts 54 are the circular flanges or sides 56. Diametrically opposite from the shaft 48 the plate 38 is provided with a recshafts 31 The upper 1 I Ytheabove referred to tape reels 58.

The operationof the; device as a as follows: The tape freel having wound thereon a supp1y o' f tape with the .iasbestos fiber deposited thereon as received from the, carding'm ac'hin'e is's'ecured upon the stud 58 2 scribed. The tape is now carried around the driving pulley 43 whlch drives said tape by frictional contact, and thence over the roller 45. The tape then passes to an empty tape reel mounted upon the shaft 48 rotated by the belt 50. It will beseen that as the tape is unwound from the reel it is always drawn toward the roller 44, the reel of tape always keeping close to the roller 44 by reason of the movement of the box 57 in the radial slot 55. Only a small portion of the coated surface of the tape is therefore exposed to the wire, thus preventing the asbestos fibers from moved therefrom. As the plate 38 is revolved about the traveling wire 3, the tape is simultaneously the other with its deposited asbestos 3. This wire 3 having previously been,

coated with adhesive composition, the asbestos fiber will be deposited thereon in the form of an overlapping spiral which may be regulated as to the number of wraps per inch and the amount of fiber deposited by the speed at which the wire 3 is madeto progress through the device. As the tape leaves the wire 3 after having theasbestos fiber removed therefrom it is wound upon the empty reel on the shaft 48 which is revolved by the belt 50 in such a manner that the slippage of the belt will compensate for the increasing diameter of the tape upon said reel due to the more positive feed of the driving pulley 23. When the tape is exhausted-the empty reel 28 is transferred to the shaft 48. A full reel is then placed upon the stud 58 and the operation repeated.

Having thus described my invention what I claim as new and desire'to secure by Letters Patent is 1. A device for applying asbestos fiber to conductors, comprising a housing mounted in axial relation to and surrounding said conductor, a circular carrier surrounding said conductor and rotatably mounted within said housing, an internal gear secured to said housing in axial relation thereto, a shaft mounted in the body of said carrier with its ends extending therefrom, a pulley secured upon one end of said shaft and a a t naaggies in, Ma at a-ape asbestos coveredlltape p lf id slii d, 1 E63 jatlyg ecerautont i w1th the flange 56 removed therefrom ;;The Q end of the tape is broughtupiandover the. roller 44 where it will-be in contact :with the Q wire or conductor 3 as the latter progresses through the orifice 39 as previously d,e.-
